Problems solved by technology

However, as some transmitting devices and receiving devices can support higher output power than 5 W, there may be a mismatch of the maximum power supported by the transmitting and receiving devices in the wireless power transmission system.
Moreover, if both the transmitting and receiving devices operate with 5 W maximum, regardless of their maximum power supports, there may be a waste of resource or a loss of efficiency since both the transmitting and receiving devices may support a higher power, e.g., 10 W.

Abstract

Method and apparatus for a receiving device to wirelessly receive electric power from a transmitting device. A power capacity is configured at the receiving device, based on a default power capacity known by both the receiving device and the transmitting device. A first value of a dependent parameter is read. The dependent parameter is associated with the electric power and varies in accordance with an independent parameter adjustable by the transmitting device. A second value of the dependent parameter is then read. A maximum power capacity of the transmitting device is identified based on at least the first and second values and a predetermined threshold. The electric power is then received from the transmitting device.

Description

BACKGROUND[0001]1. Technical Field[0002]The disclosure relates generally to a method and apparatus for wirelessly receiving power.[0003]2. Discussion of Technical Background[0004]Wireless power transmission is the transmission of electrical energy from a power source to an electrical load without interconnecting manmade conductors. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods include electromagnetic radiation in the form of microwaves or lasers and electrical conduction. Wireless power transmission has been used for battery charging, or other suitable loads, in a wide range of mobile devices, such as mobile phone, camera, music player, headset, etc.[0005]In a wireless power transmission system, the receiving device (receiver) may provide control information to the transmitting device (transmitter) by, for example, load modulation on the power signal. Based on the received control info...
